How to drop out of school and go live your dreams. Haha
<span>A dichotomous key is very easy to use because it provides only two choices. </span>
Answer:
In glycolysis, the generation of ATP takes place at the time of the transformation of 1,3-bisphosphoglycerate to 3-phosphoglycerate and at the time of the transformation of phosphoenolpyruvate to pyruvate. However, when arsenate is used in place of phosphate it results in the generation of 1-arseno-3-phosphoenolpyruvate to pyruvate that further gets dissociated into 3-phosphoglycerate without generating any ATP.
However, in the process, the transformation of phosphoenolpyruvate to pyruvate does not get hampered, and therefore, the reaction will produce two ATP from one glucose. Although at the time of the preparatory phase of glycolysis, two ATPs are used that signifies that the net gain of ATP will be zero.
The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.
